EVALUATING DIABETIC RETINOPATHY SCREENING INTERVENTIONS IN A MICROSIMULATION MODEL
2020 WINTER SIMULATION CONFERENCE (WSC), pp. 944–955.
TL;DR:
A microsimulation integrating the natural history model of DR with a patient’s interaction with the care system increased adherence of patients with vision-threatening DR to follow-up eye care, decreased the number of ‘unnecessary’ visits in specialty eye care from patients without VTDR, and decreased the total years spent blind.
